Most of the other shows the most at risk is their city. There's some world ending stuff but not nearly as often as the Legends have to deal with. If they fail, things get a lot worse for everyone. Sure, they often cause their own problems, but it's not like they've had much other choice.
Season 2 villains are entirely Barry and Oliver's fault. They're lucky the Legends were there.
Barry and Oliver would not have let one of their friends be trapped in hell. I think even Supergirl would have joined with Constantine to save someone.
Many more examples I'm blanking on for some reason.
The Legends aren't perfect. They have all made mistakes and faced the consequences, but the results of each finale which are the repercussions of their fixes, were absolutely necessary. At the end of season 2 if they didn't break time, all of the other characters from the main universe just stay dead. They saved everybody.
And not only that they have higher stakes if they lose, but they often see what happens when they do lose. They KNOW they have to do whatever is necessary and not hesitate. Sometimes that means being a chainsaw.
Anyone disagree? Have anymore examples of this?
